Abstract

Des conceptions de signaux de référence de suivi destinées à des déploiements sans transmission continue de signaux de référence sont décrites. Les signaux de référence de suivi peuvent être étendus dans le domaine fréquentiel à partir d'un bloc de signaux de synchronisation et peuvent occuper un sous-ensemble ou l'ensemble des périodes de symboles du bloc de signaux de synchronisation. Les signaux de référence de suivi peuvent avoir le même espacement de sous-porteuse que celui des signaux de synchronisation et peuvent être perforés dans le domaine fréquentiel. En variante, les signaux de référence de suivi peuvent comprendre des signaux de référence de commande communs transmis périodiquement avec des signaux de référence appariés dans un canal de données. Les signaux de référence de commande communs et les signaux de référence appariés peuvent être transmis indépendamment de la présence de commande ou de données. Pour un suivi amélioré après une transition vers un mode connecté ou un cycle de réception discontinue (DRX) long, un créneau comprenant des signaux de référence de suivi peut être répété, ou un motif de signaux de référence de suivi supplémentaire peut être transmis.
